Developmental Biology

Organoids help researchers understand biological processes in health and in disease. It is, however, difficult to influence the way in which they organize themselves into complex tissues. Now a group led by Nikolaus Rajewsky has found a new way to do so. They report their work in Nature Methods.

It borders on the miraculous how an entire animal emerges from a single egg cell. In order to understand the underlying molecular mechanisms, Markus Mittnenzweig is establishing the Computational and Developmental Biology Lab at the Max Delbrück Center.

Behavior can be observed in the brain. Swedish neuroscientist Hanna Hörnberg looks for the molecular and cellular changes that occur in the nerve cells of people with depression or neurodevelopmental conditions – and hopes to create new basic knowledge that can help diagnosis and guide support needs.

Genes are not the only drivers of evolution. The iconic fins of skates are caused by changes in the non-coding parts of the genome and its three-dimensional structure, a research team including Darío Lupiáñez at the Max Delbrück Center reports in “Nature”.

The Max Delbrück Center wants to shape the future of medicine through innovation. But turning basic research into marketable products requires gaps to be bridged. This is achieved by the Technology Transfer Office – through funding schemes such as BOOST and Pre-GoBio. The winning projects for 2023 have now been selected.

Evolutionarily young miniproteins are unique in humans, and researchers have recently discovered thousands of them. Writing in Molecular Cell, Norbert Hübner and colleagues from the BIH and other institutions describe the origins of these tiny proteins and explain that they probably influence important cellular processes.

Muscle cells are very good at repairing damage. But if this fails, stem cells step in to regenerate the tissue. Carmen Birchmeier investigates the molecular signaling pathways that underlie these and other vital mechanisms.

Mammals possess a gene that controls a novel structure in nerve cells. Researchers at the Max Delbrück Center and the Milner Centre for Evolution have discovered it and describe it in the journal „Molecular Biology and Evolution”.

An international consortium brings together 7,200 segments of the human genome that are virtually unexplored and presents a roadmap for integrating them into genome databases in “Nature Biotechnology”. They could hold information about what sets humans apart from other animals.

The way the genome is folded regulates gene activation, so it can’t be left to chance. Molecular boundaries across the genome keep things in order. A team led by MDC researcher Darío Lupiáñez has discovered how these boundaries work. Their findings, published in "Nature Genetics", could help us to better understand developmental diseases or cancer.
